Getting to know planets with the help of Professor Sabine Stanley and images gathered by NASA; offering a fuller picture of what scientists know about the solar system; how much there is yet to learn.
EPISODE 1
How the Solar System Family Is Organized
Since 1962, robots traverse the solar system; exploring a family album overview of planets, dwarf planets, moons, asteroids, Kuiper Belt objects and long-period comets; flying through some of the solar system's most unique features.
EPISODE 2
Mercury, the Extreme Little Planet
Mercury is a planet of many solar system extremes. It's the smallest planet, the closest to the Sun, and it has the shortest year, most elliptical orbit, smallest axis tilt, and largest fraction of iron. Learn how these characteristics have resulted in a planet where the Sun sometimes moves backwards across the sky, and where water ice has been found at the poles.
EPISODE 3
Venus, the Veiled Greenhouse Planet
While the Venusian carbon dioxide atmosphere has resulted in a runaway greenhouse effect and the hottest surface temperature in the solar system, the Earth and Venus actually contain about the same amount of carbon. Explore the forces that resulted in the extreme atmospheric differences between these two otherwise-similar planets.
EPISODE 4
Earth: How Plate Tectonics Sets Up Life
Given the striking similarities between the four terrestrial planets, why is Earth the only one teeming with life? Proposed as a bold theory less than 70 years ago, could plate tectonics be a main driver of life on Earth? Explore the fascinating movement of our planet’s surface and the many ways in which a geologically active Earth has sustained our biologically active planet.
EPISODE 5
Orbiting Earth: Up through the Atmosphere
Compared to Venus or the giant planets, Earth has a relatively thin atmosphere. And yet, without this single, fragile layer, life would not have evolved and thrived. Discover the unique properties of each atmospheric layer, and encounter specific ways we’ve explored each layer as a springboard to exploring the rest of our solar system.
EPISODE 6
Exploring the Earth-Moon System
Our Moon, formed from the Earth about 4.5 billion years ago, is by far the largest moon in the solar system relative to its planet’s size. Explore the many ways in which this uniquely coupled system affects the tides on Earth and on the Moon, our rotation and revolution, the process of tidal locking, and even the planetary stability that has allowed for the development of life on Earth.
